For 2.29 hours that's ~137 minutes.

Divide that by sixty again using whole numbers and the remainder is 17 minutes.

You end up with 2:17.

Unfortunately you currently can't do that calculation in the template language. All the arithmetic is floating point.

I am going to add some more math functions: floor(x), ceiling(x), fractional_part(x), round(x), and mod(x, y). Using these (when they are released), you will be able to compute hours:minutes from fractional hours using something like this template.

program:
# total_hours should be a field reference
	fractional_hours = 3.6982;
# Compute the number of hours in total minutes as an integer
	display_hours = floor(fractional_hours );
# Compute the number of minutes left over after display_hours
	display_mins = round(multiply(fractional_part(fractional_hours ), 60));
# Format the results as h:mm
	strcat(display_hours, ':', format_number(display_mins, '02d'))

This template produces the result "3:42"
